1 Claim.

My invention relates to rotary pumps and one object is to provide a pump of this character in which the impeller is so constructed as to have powerful suction qualities whereby it is enabled to economically pump oil, water or other liquids from deep wells or other sources.

A further object is to provide a rotary pump in which the working parts are automatically controlled so thatvery little if any attention is required on the part of an attendant.

Other objects will hereinafter appear, and in order that the invention may be fully understood reference will now be had to the accompanying drawings, in which:

Fig. 1 is a front elevation of the pump.

Fig. 2 is an irregular vertical section on line 2-2 of Fig. 1.

Fig. 3 is a central vertical cross section of the pump.

Fig. 4 is a detail front elevation of one of the Y-couplings or manifolds employed in carrying out the invention.

Fig. 5 is a detail perspective View of a packing ring.

Fig. 6 is a broken horizontal section of a pair of valves on line 66 of Fig. 3.

Referring in detail to the different parts, 2 designates the cylinder of the pump which consists of two sections 4 and 6 having parallel side Walls and secured together at their abutting portions with suitable means such as bolts 8 and provided at their lower portions with outturned base members Ill and I2 bolted or otherwise firmly secured to a bed plate l4.

l6 designates a rotary impeller which operates in an annular chamber l8 formed within the sections 4 and 6 of the cylinder 2. The impeller I6 is provided near each end. with a split packing ring 20 fitting snugly within the chamber l8 to enhance the suction quality of said impeller so that it may economically draw oil, water, or other liquids from deep wells or other sources.

The impeller I6 is fixedly mounted upon a radial arm 22 projecting from a hub 24 fixedly mounted upon'a drive shaft 26 journaled in a plurality of bearings 28 secured upon the bed plate l4. The shaft 26 is prevented from shifting longitudinally within the bearings 28 by a pair of collars 30 fixedly mounted upon said shaft 26 and arranged adjacent to the intermediate bearings 28, Fig. 1. The shaft 26 is equipped with a fixedly mounted gear wheel 3| which may be driven from any suitable source (not shown) as a steam engine, electric motor, or the like.

The arm 22 extends through an annular slot 32 formed between the two cylinder sections 4 and 6. Said slot 32 is closed by a split packing ring 34 provided near its ends with transverse notches 36 into which the rings 20 project and thereby cause said packing ring 34 to rotate with the im- 5 peller IE5. The packing ring 34 travels upon annular shoulders 3'! forming the sides of the slot 32 and prevents leakage of liquid through said annular slot and out to atmosphere through a circular opening 38 formed in the central por- 10 tion of the cylinder 2. The packing ring 34 is prevented from being forced too tightly into frictional contact with the shoulders 3'l by suitable means such as a plurality of set screws 40 threaded in a split ring 42 which is spaced from but ar- 15 ranged concentrically within the packing ring 34, Figs. 2 and 3.

After being properly adjusted the set screws 4B are firmly secured by lock-nuts 44 which are adjusted into engagement with the inner periphery 20 of the split ring 42, the ends of which latter abut opposite sides of the arm 22 in order to rotate therewith. The packing ring 34 is provided with a plurality of small transverse openings 46 through which liquid entering the chamber I8 25 may pass and lubricate the contacting surfaces of said packing ring 34 and the shoulders 3i.

Liquid is sucked by the impeller l6 into the annular chamber l8 through inlet ports 46, formed in the lower portion of the cylinder sections 4 3 and 6, and is forced by said impeller through outlet ports 59 formed in the lower portion of the cylinder sections 4 and 6. The inlet ports 48 communicate with a Y-coupling, or manifold 52 connected to an inlet pipe 54 which extends into the 35 well or other source from which the liquid is being pumped. The outlet ports 59 communicate with a Y-coupling 56 connected to a discharge pipe 58 which conducts the liquid to any desired point. As shown by Figs. 1 and 4 the coupling 56 has 40 two oppositely disposed parallel flanges adapted to fit against and be firmly secured to the parallel side walls of the cylinder 2.

In order to cause the liquid to flow through the annular chamber l8 and out through the outlet ports a pair of valves Ell and 62 are interposed between the inlet and outlet ports 48 and 5&3, respectively. As more clearly shown by Fig. 3, the valves fill and 62 are reciprocably mounted in housings 64 and 66 which are prefer- 50 ably formed integral with the lower portion of the cylinder sections 4 and 6 and provided with removable caps 68 and It equipped with leak-proof stuffing-boxes l2 and 14 through which stems I6 and 18 of the valves 60 and 62, respectively, project. The adjacent ends of the valves 60 and 62 are arranged to overlap when closed, as shown by Fig. 6, and thus form a leak-proof joint and their upper adjacent portions are recessed as indicated at 80 to snugly fit against the packing ring 34 and form a leak-proof joint.

Leakage of liquid around the upper and lower edges of the valves 6!! and 62 is prevented by packing elements 82 and B4 forced against the adjacent surfaces of the housings 64 and 56 by springsflfi and '88, respectively, which latter also force thevalves 58 and '62 againstthe upper portion of the respective housings 64 and 68.

As a further precaution against leakage of liquid around. the valves 60 and 62 the --side of said valves nearest the inlet ports 48 are pressed against the adjacent sides of the-housings 64 and 65 by means of springs 99 and I036, which also press packing elements I82 and I04 against the opposite sides of the housings 64 and E8, respectively.

The outer portionsof the valve stems I6 and H3 are vreciprocably mounted in slideways I58 and I98 mounted upon the bed plate I 4. Said stems I6 and I3.are reciprocated by means of cams I M and I I6 and antifriction-rollers I i8 and I29, which latter are :mounted upon spindles I22 and 324 secured to thevalvestems IE3 and 78, respectively. The rollers H8 and I29 extend into peripheral grooves I30 and I32 formed in the respective cams H4 and -I I6. Said grooves I39 and I32 have lateral extensions I34 and I36 which upon engaging .the rollers 'I I8'and I20 force the latter toopen the valves 50 and-62 through the intermediary of :the stems 1.6 and I8 to permit the impe1leri20 to pass,-after which they immediately close said valves, so that liquid drawn into the chamber I 8 by the impeller will be forced through the outlet ports 50.

With the foregoing arrangement it is apparent that the operation of the pump is attended with 5 but little friction and a steady stream of liquid is forced from the pump during the operation of the impeller 20.

From the foregoing description it is apparent that I have provided a rotarypump embodying 10 the advantages above pointed out, and while I have shown one form of the invention,'I reserve all rights to such changes and modifications as "properly fall within the spirit and scope of the invention as claimed. 15 Having thus described my invention, What I claim'and desire to secure by Letters Patent, is:

A rotary pump comprising a cylinder with parallel side walls having inlet ports at its opposite sides and outlet ports at its opposite sides 20 and close to said inlet ,ports, arone piece Y-shaped manifold straddling .the cylinder and communicating with-said inlet ports, a -\I-shaped manifold straddling the cylinder and communicating with the outlet ports, :parallel flanges on said 5 manifold adapted to fit snugly against and be firmly secured to the parallelside walls-of the cylinder, a rotary impeller operably .mounted within said cylinder, reciprocatory valves extending transversely through the cylinder and 0 located between the inletand-outlet and means .for opening .the valves to allow the impeller .to pass and to close said valves after passage of said impeller.
